MTJEEE JOHN ST. CLAIR, OF PUNXSUTAWNEY, PENNSYLVANIA.

STICK-PIN FASTENER.

Specification of Letters Patent.

Patented Aug. 12,1913.

Application filed June 3, 1912. Serial No. 701,244.

To all whom it may concern:

Be it known that I, JOHN ST. CLAIR, a citizen of the United States, residing at Punxsutawney, in the county of Jefferson and State of Pennsylvania, have invented certain new and useful Improvements in Stick-Pin Fasteners, of which the following is a specification.

My invention relates to stick pin fasteners and has for its object the provision of a device to prevent the accidental displacement of a stick pin from the necktie or other article of wearing apparel.

The invention consists in the provision of a spring clamp constructed of a single strip of metal bent to the proper form and having alined openings to receive the stick pin, the metal being bent on itself where it engages the pin and so constructed that the two portions of the part bent on itself tend to engage the two sides of the stick pin diametrically opposite to each other with sufficient force to prevent the accidental displacement of the clamps.

My invention will be described in detail hereinafter and illustrated in the accompanying drawings, in which- Figure l is a view of a stick pin showing my improved clamp in position thereon, Fig. 2 is a similar view taken at a point ninety degrees removed from the position of the view shown in Fig. 1, Fig. 3, a longitudinal sectional view of the clamp removed from the pin.

In the drawings similar reference characters will be used to designate corresponding parts in all the views.

A indicates a stick pin of the ordinary structure showing my improved clamp thereon and designated generally at l. The clamp 1 comprises a single piece, or strip of metal formed with a tongue 2, the metal then bent back on itself as shown at 3 and after being continued for a short distance formed with an outwardly projecting undulation 4 then continued in the direction of the free terminal of the tongue 2, then bent outwardly from the tongue on a wide curve as shown at 5 and continued toward the undulation 4, then bent into an undulation co'rresponding to and substantially parallel with the undulation 4, said last described undulation being designated 6, and the end of the strip as indicated at 7 terminating substantially opposite the bent back portion 3. The undulated portions 4 and 6 are formed with alined openings designated 8 and 9, respectively, that aline when the two parts of the metal strip where undulated are pressed toward one another to receive the stick pin A, and when pressure is released the two parts of the strip where undulated tend to spring apart and the edges of the openings 8 and 9 by engaging the pin tightly clamp the pin and prevent the fastener from accidental displacement.

In operation the clamping member 1 is placed upon the pin when the parts are squeezed between the thumb and finger, one of the members of the hand engaging the tongue 2 and the other member engaging the undulation 2 and the pin inserted through the alined openings 8 and 9. After being placed upon the pin when pressure is released the parts at and 6 spring apart and securely clamp the member thereon. To remove the clamping member from the pin the device is grasped in the same manner as heretofore described and squeezed together so that the pin may be removed.

It will be understood from an inspection of the drawings that my improved fastener may be readily removed and replaced on t e pin and when in position on the pin will prevent loss thereof because of accidental. withdrawal from the article of apparel.

Having thus described my invention what I claim is:

1. In a stick pin fastener, a strip of metal bent to form corresponding and substantially parallel overlying portions having undulations therein, the two sides of said undulations provided with alined openings adapted to receive the stick pin, and an integral tongue extending from the free end of .one of said portions and engaging the other end of said portion.

2. A stick pin fastener formed of a single strip of metal, said strip of metal having one end forming a tongue, the strip then bent back on itself and provided with an undulation extending outwardly from said tongue, the strip then bent away from the tongue on a curved plane and back toward 59, i,oto,o75

the undulated portion aforesaid, the strip then formed With an undulation corresponding to the first mentioned undulation, the terminal of said strip being substantiallyopposite the first mentioned bent back portion, and the tWo undulations formed With alined openings adapted to receive the stick pin, said two undulated portions normally tending to move from one another to clamp the fastener on the stick pin.

In testimony whereof I affix my signature in presence of tWo Witnesses.
